|Location and accuracy||The occurrence is at an elevation of about 2,100 feet on a divide halfway between Kanaktok Mountain and VABM Chevron (Grybeck, 1977). It is in section 34, T. 29 N., R. 5 W., of the Kateel River Meridian.|
Geologic descriptionThis occurrence consists of sulfide-bearing quartz lenses in Upper Devonian phyllite (Schmidt and Allegro, 1988). The lenses contain pyrite, chalcopyrite, and a little malachite. The mineral-bearing zone occurs in an area of about 100 feet by 6 feet. Assays of grab samples indicate an average grade of 0.37 percent copper (Degenhart and others, 1978).

|Mineral deposit model||Kipushi Cu-Pb-Zn (Cox and Singer, 1986; model 32c).|
|Mineral deposit model number||32c|
|Age of mineralization||Devonian?|
|Workings or exploration||The site has been visited and sampled by the U.S. Geological Survey (Schmidt and Allegro, 1988) and U.S. Bureau of Mines (Degenhart and others, 1978).|
|Indication of production||None|
|Reserve estimates||The inferred tonnage and grade are very small. The potential for significant tonnage of material assaying more than 0.4 percent copper is considered remote (Degenhart and others, 1978).|
Additional commentsThe occurrence is located in the Noatak Wilderness of the Noatak National Preserve.
